Well, that would be evidence for macro-evolution. The evidence against macro-evolution in the fossil record is that we see long periods of stasis, followed by the sudden appearance of new forms.

Species that are well adapted to environments will remain as along as that environment persists and long periods of stasis in common in the fossil record of life. It is not a problem for evolution. Some species have persisted for millions and if not billions of years, because they well adapted to a given environment, though some may evolve as new environmental niches are available. The evolution of species is a response to environment changes, competition for survival, and new environmental opportunities.


As far as birds in Cretaceous there were many species of small dinosaurs with feathers, avian dinosaurs, and birds of various lineages which after the great extinction event only some branches of birds survived and they show a rapid diverse evolution after the extinction event. I believe there are more diversity and intermediates and there are more found all the time.

After the great extinction event apparently there were at least three groups of orders of main class of birds that survived, The Ratites,
Anseriformes (duck billed birds) and the rest of the bird orders. All the forest dwelling birds of the time apparently did not survive of the time did not survive, and the surviving birds evolved and adapted to forest environments..

"Sudden" is an extremely relative term. In the geologic record "sudden" might mean over the course of hundreds of thousands or even more than a million years.

I should also point out that there really is no doubt that macroevolution took place and continues to take place as it has been repeatedly been observed both in nature and the lab. You see speciation, which is when a lineage splits into two or more genetically distinct groups, is a form of macroevolution^[1] and occurs so often that even the major Young Earth Creationist (YEC) groups have abandoned the claim that it does not take place and a few even fully embrace it with at least a couple of them now relying on it as an explanation for how a boatload of animals could be responsible for the incredibly wide diversity of lifeforms that inhabit the planet today.






1. macroevolution by definition is evolutionary change AT or above the species level.

One of the reason I pick birds as an example of macro evolution is the vast amount of intermediaries and the variety of species in the fossil record evolving from feathered dinosaurs to avian dinosaurs to birds. China's vast finds of near perfectly preserved examples over a period of millions of years in slates primarily from lake sediments in volcanic regions during the periods birds evolved, and more are being discovered all the time. I have been to the primary sites in Liaoning Province, China where most of these discoveries were made. Fossil hunters are blessed by vast amount of species asphyxiated by volcanic gases and fall into the lakes and quickly covered with ash. The finds in the rest of the world like Germany fill in many of the gaps in the fossil record.

My favorite is the transition from primitive amniotes to mammals via the synapsids, commonly referred to "mammal-like reptiles." The record is so complete that there is spirited debated over whether to categorize some as "mammal-like reptiles" or as "reptile-like mammals."

Yes, this is a good example. I object the concept of a 'sudden appearance' of species, because this only based on the limitations of fossil finds and 'argument from ignorance' asserting, because there are no fossils found at present there is a sudden unexplained appearance.

I thought I would add here the reason for the appearance of 'is that we see long periods of stasis, followed by the sudden appearance of new forms.' reflects the limited finds of fossils over time that reflect this illusion of 'missing links' in periods of apparent stasis. Over time more and more fossil finds indicate that the 'long periods of stasis' in reality do not exist, and a wide variety of related species and subspecies existed in more of a continuum in time of evolution as in the evolution of birds, and early evolution of mammals..

[shunyadragon]

In terms of the birds there are many recent discoveries that demonstrate the diversity of related species and subspecies existing in a continuum of evolution.

Translate: They are finding parallel evolution of several avian dinosaurs developing the ability for flight.

Well, I was quoting an evolutionist, from "Beak of the Finch." Long periods of statis do exist, which is why evolutionists have come up with "punctuated equilibrium" as a description of the fossil record.

Actually Darwin predicted that there would be periods of stasis since organisms will evolve at different rates pretty much from the get go.

Again, yes, that is what is described by the limited fossil finds with of course gaps in the finds. You have neglected the facts that the concept of 'punctuated equilibrium' is based on millions of years, plenty of time for evolution to take place at leisurely pace. Please note that the book observed that by the present evidence at the time there were gaps that indicated stasis, and not the conclusion, and not the conclusion that stasis was not the fact.

A more contemporary approach based on more fossil evidence throughout the geologic history of life, like the evidence for the evolution of the birds there was a great variety of variations and subspecies existing at the same time the evolution of bird-like dinosaurs to birds took place based on the discoveries since the book was published. We are now dealing with many species, cub-species and varieties living at the same time throughout the Cretaceous along with birds in the late Cretaceous. This great variety of related species, subspecies and varieties is common in among animals and plants in today's rain forests.

The "Beak of the Finch" is 1995. Kind of old concerning the present knowledge of an immense more fossils discovered since including many more fossils of bird like dinosaurs, avian dinosaurs, primitive birds and birds in the Cretaceous creating a detailed picture of continuous evolution from dinosaurs to birds.

An interesting example is the evaluation of old discoveries. In the slates where the first archaeopteryx was found they also found a complete feather they thought belonged to the archaeopteryx, but based on further discoveries it was found to be a more evolved avian dinosaur with bird flight or a bird's feather that lived at the same time as the Archaeopteryx.
